Question

Select the correct statements for diborane :
(i) Boron is approximately $s p^3$ hybridized.
(ii) $B - H - B$ angle is $180^{\circ}$.
(iii) There are two terminal $B - H$ bonds for each boron atom.
(iv) There are only $12$ bonding electrons.

• A. (i), (ii) and (iv)
• B. (i), (ii) and (iii)
• C. (ii), (iii) and (iv)
• D. (i), (iii) and (iv)

Answer 1

Answer: (D)

$B$ is $s p^3$ hybridized
Only $12$ bonding electrons available
$BHB$ angle is $97^{\circ}$ not $180^{\circ} .$
